Parksosaurus ("William Parks's Lizard") was a relatively large hyspilophodont ornithopod dinosaur, around 2-4 meters long, related to Othnielia, named after William Parks, the palaeontologist who discovered it first in 1937, and it was one of the last of its family, living at the end of the Age of Dinosaurs. Found in Canada (72-65) it had blunt, peg-like teeth, suited to chewing thick leaves and fleshy fruit.

Like other hypsilophodonts it had a tail stiffened by bony tendons. Held straight behind it, it's tail helped Parksosaurus keep it's balance. It was a smallish dinosaur - roughly around 2-4 meters long. It didn't have any particular anatomical features and was a distant relative of the bigger hadrosaurs, such as Edmontosaurus.



Parksosaurus lived during the Late Cretaceous period from 72-65 million years ago, living up until the extinction of the dinosaurs.


Parksosaurus was a smallish but relatively large dinosaur for its size, roughly around 2-4 meters long and weighed at 45 kilograms.


Like its relatives Dryosaurus, Othnielia, and Leaellynasaura, Parksosaurus lived in large groups for protection.
